Main module is both constructor and factory method, and can be used either way.
from
and to

is optional, and if not provided it defaults to current time.
Returns full years of the duration
Returns full months of the duration
Returns full days of the duration
Returns full hours of the duration

Same as years
. Returns full years of the duration
Returns trailing months of the duration
Returns trailing days of the duration
Returns trailing hours of the duration
Returns trailing minutes of the duration
Returns trailing seconds of the duration
Returns trailing seconds of the duration
Same as milliseconds
. Returns milliseconds of the duration
Returns readable representation of the duration.
When invoked without arguments (defaults to mode=0), returns as:
10y 2m 6d 03:23:08.456
When invoked with mode 1
, returns alternative representation:
10y 2m 6d 3h 23m 8s 456ms
Representation returned by default modes can be customized with threshold setting that trims lowest units:
duration.toString(); // 10y 2m 6d 03:23:08.456
duration.toString(0, 1); // 10y 2m 6d 03:23:08
duration.toString(0, 2); // 10y 2m 6d 03:23
duration.toString(1); // 10y 2m 6d 3h 23m 8s 456ms
duration.toString(1, 1); // 10y 2m 6d 3h 23m 8s
duration.toString(1, 2); // 10y 2m 6d 3h 23m
When invoked with string, formats the duration according to given pattern, where:
%y
-duration.year
%m
-duration.month
%d
-duration.day
%H
-duration.hour
%M
-duration.minute
%S
-duration.second
%L
-duration.millisecond
%ms
-duration.months
%ds
-duration.days
%Hs
-duration.hours
%Ms
-duration.minutes
%Ss
-duration.seconds
%Ls
-duration.milliseconds
%sign
- If duration is negative outputs-
otherwise empty string
